muffler bumper
« on: July 19, 2013, 00:27:18 »
I have seen listed in our parts descriptions, a type of rubber shock absorber  that goes above the rear muffler. I think it is installed above the rear muffler hanger, but I'm not at all sure. I didn't put one of these on my 250SL years ago, when replacing the muffler system. Does anyone have a photo and/or description, that shows where this goes and how it is installed. Is it only for 250 SL's, or did the 280SL use them also?

Hi Michael,
check this thread: www.sl113.org/forums/index.php?topic=18857.0
Is that what you're talking about, or something else?

A small black rubber stand-off fits above the metal bumper in a hole in the cross piece that spans the pipes.

The "point" of the black bumper goes into the hole in the pipe spanner so that the piece pushes against the metal bumper.

This is to stop the pipes from hitting metal to metal when going over rough ground.
The pipes are held up by rubber rings which can shake and stretch a bit when disturbed.

Here are a couple of rubber bumpers for you to admire.

...and here is a link to my mention of this part awhile back.  Look at "Rear Exhaust Bumper".
Some other often missing parts are also mentioned in that post.

thanks for the photos-but I would like to have better pictures that show where the bumpers actually are inserted

Does this help? I have an aftermarket SS exhaust system so the bracket might not look exactly like the MB system.

Check out the post for  "Rear Muffler - sanity check"  The second to last photo shoss the pipes and a hole in the car above the pipes - that is where the bumper goes - it mates with the flat piece of metal bracket joining the two tail pipes.   If you follow the thread you will note that the flat piece of metal on the exhaust in question is installed incorrectly and the 2nd to last photo doesn't even have that flat piece of metal.  

This is where stock systems have the fittings to mate with the car properly.
